With reference to Indian freedom struggle, which one of the following statements is correct?

1. The question asks for the correct statement regarding the Indian freedom struggle. 2. Option (A) states The Rowlatt Act led to popular indignation and the Jallianwala Bagh massacre. This is correct; the protests against the Rowlatt Act culminated in the massacre at Jallianwala Bagh in Amritsar on April 13, 1919. 3. Option (B) states Subhash Chandra Bose formed the Forward Bloc. This is correct; Bose formed the Forward Bloc in 1939 after resigning from the Congress presidentship. 4. Option (C) states Bhagat Singh was one of the founders of Hindustan Republican Socialist Association (HSRA). This is correct; Bhagat Singh, along with others like Chandra Shekhar Azad, transformed the Hindustan Republican Association (HRA) into the HSRA in 1928. 5. Option (D) states In 1931, the Congress Session at Karachi opposed the Gandhi-Irwin Pact. This is incorrect; the Karachi Session endorsed the Gandhi-Irwin Pact, although with reservations expressed by some leaders regarding the execution of Bhagat Singh, Sukhdev, and Rajguru just before the session. 6. The question asks for the *correct* statement. Statements A, B, and C are all factually correct historical events. Statement D is incorrect. However, the provided answer key is (D). This indicates a potential error in the answer key, as (D) describes an incorrect historical fact. If we strictly follow the answer key (D), we must assume A, B, and C are somehow considered incorrect in the context. This is difficult to justify. For instance, 'around' in (A) might be considered vague, 'Blood' instead of 'Bloc' in (B) is a typo in the input but likely meant Bloc, and 'one of the founders' in (C) is correct. Statement D is factually wrong. Assuming the key 'D' is incorrect and the question intended to ask for the *incorrect* statement, then D would be the answer. If the question asks for the *correct* statement, A, B, and C are all candidates. There seems to be an error in the provided information (either the question or the answer key). *Sticking strictly to the provided answer 'D' implies A, B, C are wrong and D is right, which contradicts established historical facts.*
